strange occurrences lately, family members.

I'm not a blood is thicker than water guy and I've estranged myself from several family members (not my kids) several years ago that I didn't consider trustworthy. Yesterday and today I've received several phone calls from them trying to re-establish contact.  I no longer have reason to fear them as I no longer have disposable income and they know that.
I'm not sure what's going on but I know the Bible has things to say about family. Maybe I need to read a bit and figure it out. If anyone here can point me to biblical passages relating to that I'd appreciate it.
